STOPPING MECHANISM FOR SEWING-MACHINES.

Specification of Letters Patent.

Application filed February 11, 1905. Serial No. 245,319.

To all who). '1'! may concern lie it lcnown that .l, I'IENRY C. menu, a citizen of the United States, residing at Waterford. in the county of Saratoga and State of New York, have invented new and useful Improvements in Stopping Mechzv nism for Sewing-Machines, of which the following is a specification.

This invention relates to improvements in stop mechanism in count stitch sewing machines, used for buttonholing, eyeleting and barring.

In button hole machines, it is essential when the stitching has been completed that the machine be stopped with its needle out of the fabric to facilitate the removal ofthe same and the insertion of another piece. In devices now used for this purpose, considerable dilliculty is experienced in stopping the needle at the proper point. and in some instai'ices starting the needle. Aside from these dilliculties with the stoppingand start ing oi the needle at the proper moment, other decided disadvantages exist, due to construction and the incidental operation. In my present improvement, I have sought to cure the defects noted, and have devised a mechanism, which insures of the needle being stopped at the proper time, and binding and consequent holding of the parts are dispensed with.

The prime object of my invention is to provide a stopping mechanism, automatically operated, the stitch forming mechanism running by momentum for a given period when near the end of a button hole. the speed being gradually retarded, until by the time the point of stop is reached, the speed is arrested without jarring or bindof the parts.

I l-ave found by experience with high speed button hole machines, that it is impossible to use a positive stop mechanism. or mechanism of a binding nature to retard the speed. I have therefore provided a con struction, which consists essentially of what may be termed a preliminary cushion against whicha projection on a revolving part of the operating mechanism strikes.

after the power has been cut offfand a final cushioned stopping device to receive the pro ection as it leaves the preliminary cushion to hold the stitch forming mechanism from further movement. f The parts are so located that by the time the preliminary cushion acts on the power mechanism little or no momentum force remains, and the linal stop holds the stitch forming mechanism in a predetermined position. This retarding ell'ect is further accomplished by reason of the fact that the preliminary cushion also acts on the power mechanism after the latter leaves the former, and just at the time the final stopping device is actuated.

Other objects and advantages will be hereinafter referred to and be particularly pointed out in the claims.

In the drawings, Figure 1 is a view in side elevation of a conventional button hole sewing machine, showing my improvement applied thereto. Fig. 2 isan enlarged side elevation of my invention.

The numeral 1 indicates a button hole sewing machine, comprising essentially a power shaft 2, with fast and loose pulleys 3 and i; needle bar 5; holding lever e; starting bar 7: belt shifting lever 8; stopping lever 9; and automatic means 10 for throwing the stopping mechanism into position. On the starting bar '7 is a coiled spring 12, lo-

catcd between the sewing machine frame and l The general construction of the parts de V scribed is well known in the art, and forms no part of the present invention, except in oomhi imrirovetl' stopping l3; wing memb E31 adapted to it from the *t 26 having fiau s 2'? which goiales for mechanism. about to he described, bar

28 operates between the guides, and its upeiri 38, is bevelecl shown in ttached to its lower end is a spring 30,

e end of the spring screw 81, having a in a adjuster, lug proj secom is seem: t formed into a loop which surrounds v D 29 but normally out oi contact therewith The purpose it this oonstruction is to ally retard the momentum of the pmver shaft, When the projection strikes the end of bar 28, it meets with little resist ance, but as the bar is forced clown tension of spring 30 is increased, until the lug contacts with the loop' of t! J enlarged spring which otlers suliicient additional re sistance to further, but graduall" retard the momentum the power shaft and the mesh anism thereby. As the motion of the power shaft continues, and it resists the tension of the two springs, and to further augment the retarcling effect, the projection in its rota tion. must force itself up the beveled. end 2232*, prior to its release from the bar the cast t consider to the lug;

lo t e revolution. of the projection. 25, it leaves the bar 28 and the latter immediately flies back under the influence of the springs to normal position, the blow being relieved. by a oush ion 34, The bar 28 is retained between the guides by a plate 35, as will be readily understood. it pin passes freely through an openingv in the bar 28, and it has formed on one end a head 36 which is normally spaced from theiouter eclge of said bar, to form a seat 37 which is normally slightly narrower than the diameter oi the projection The opposite earl of the pin 36 threaded to I: receive nuts 38 a washer 39 and encircling the pin between the washer and the outer Wall of the'oasting Boris a spring The pin and the parts just described in eonneetion therewith, form What I have termed the final cushioned stopping device, and-eonstitutes an important part of the invention. The proportion of the seat 87, relative to the in 25 has a further function; in that the pin 1s;prevemecl from engaging the seat should the stopping mechanism be slow in positioning itself thepath of the Untiersuch cireumstane s the sin seat adjustably seourecl to free shifting on their pivots as shown in FW. 3, which eoulol not engage the and would it, shown clearly 111' 9. i .ien starting the sewing machine, the perator pulls (lows the lever 15, which moves the starting bar 7 outv:1rclly, oompressmg spring 12 and placing a lug l0 l1].

osition for the notched entl of the holding lever 8 to engage, to hold the stopping mechanism in set position during the period of forming a button hole. The movement of bar 7, simultaneously rocks the belt or 8, and the stopping lever 9,

shifts the belt 22 from the loose to the fast pulley, and disengages the projection 25 from its 3?. Motion having been applied by this operation to the power shaft 2, the stitehin of the button hole takes place, The button. hole having been corm pletecl, the automatic mechanism strikes lever 6, and (lisengages its end from the lug ll) and the spring 12, throws bar 7 towarol the which brings the casting 26 and its part against the flange 9:4, throws the belt from the-fast to the loose pulley, the power shaft, then being run by IDOHEGKL" tum the balance Wheel 23 assistin The ivots of the levers 8 and 9 are located with relation to the connection with starthat '7 so that when the stopping mocha" to be operated the belt shifter shows the bolt from the fast to the loose pulley in advance of the engagement of the pin E with the bar 528. This absolutely insures the stopping mechanism overcoming the resistance of the momentum, and "not power, as would be'the if the pin enthe stopping mechanism when the belt I was on the fastpulley. The stopping mechanism nowbeing in the path of the projection. 25, and latter being propelled by 28 of the bar shown in Fig. 5, and exerts tension on the preliminary-springs 80,

and as the movement oi": the projection-progresses, it eontihues to depress the bar which gradually eonta'ets with larger spring, and increasing the tensiom and. CO1S8qlIl1tl retarclint the movement of the ower shaft the pin in the zi'ieantime ricles down the bevelecl end 28, until a pproximately a line 'drawn through the center of the shaft is reached shown in 6. The momentum of the driving mechanism by this time is niomentum, first strikes the bevelecl end" Fig. 7, the momentum of the power shaft is almost lost, but it is essential that it he gradually and lirmly stopped at a predetermined point, to properly locate the needle as hereinbetore pointed out. The head is in the path of travel of the projection 25, and as soon as the latter leaves the top of the bar Lo and travels across the seat 37, it contacts with said head, and in'nncdiatcly the bar 2 is returned to its normal position, and in so doing, and while the projection is in the 'seat 37, the outer edge of the bar contacts with the projection and materially assists in preventingits :l'urther rotation. llow ever, this action is incidental, the projection once having reached the seat 37 it contacts with the head. and the spring, is ol such strength as will ell'cctually receive the final blow oi the projection. and while it. may yield somewhat, .it returns again, together with the projection to normal position,

shown in Fig. 8. The parts are so related that when theprojcction 25 is caught in the seat 37 between the bar 2 5 and the head, the needle bar is elevated and the operator can quickly 'n'ocecd to introduce the no): article to receive a button hole.

-l have found that I can produce a neat, durable, and cll'ective stop iing mechanism for a sewing, machine, by placing; the operative parts so that the projection J5 maliea about one third ol a row olution by momeutum, and during this period retard and ,(wentually stop the stitching mcchanh-sm at the desired point. without in any wise jar ring or jamming the parts. i also provide and. arrange the mechanism with relation to the stopping projection so that in the event the automatic means ll) should disengage the lever l; 'l'roni the lug ill, and p rmit Ll; f stopping mechanism striking said projao than the latter will not he broken oil'. it the stopping mechanism should be slow in being released the projection will ride against the side of the casting); and push it away. and then when the pin passes by, said casting; under the influence ol' the spring;- 12 will he returned to its position in the path or" the projection, the latter limiting: a full revolution and then engaging the bar.

,ln thcfmiidilication shown in Fig. 13, the mode ol "conmmting the springs 3H and 533 are slightly dill'crcnt; the screw Ill being at the bottom, and the lug 29" being at the top.

In .lfigs. 14 and 15, the final cushioned stopping device is slightly dill'erent than that shown in the other figures. but the result obtained is substantially the same. In these figures, 4-3 indi rates a strong flat spring, the upper end being in the path of the pin and forming a head. at, a space being formed between the bar E3, and the 'head -ll to form a seat 37*. In the travel of the projection 25, it depresses the bar 12% and graiilnally leaves the latter and entors the seat 37, and is cushioned by the head ill, in rsuhstantially the same manner The construction dcscrihcd produces a st pping mechanism which lullils all the essential practical requirements to cllcctlrally stop the mechanism without undue jarg.

gradually reduce the lllflll. speed of the nnmhanisui ton complete slop in the SllUI'test possible time without disarranging the delicate adjustment of the parts; and stop the mechanism with very little recoil to prevent breaking or the thread.

Another decided important result is accomplished by my improved construction,

operating rods. which amounts to rerylittle.
